Well after not being happy with the lights in Cheri's Red Sea Max, I will be retro fitting T5's in the factory hood. We really wanted to go with LED's but right now our major budget (or lack of...) is for my upgrade from my 58g to a Custom 120g...So for now, I will be fitting the T5's for more aggressive lighting. It is amazing that Cheri has been able to keep a few high-light corals...SPS, Acans and a Blood Red Cyphastria with the factory PC's. I will be posting pictures along the way...
